Folks,

Have done my fair share of searching on this and other forums, can't seem to get to a specific answer to my question: Can I install the R56 JCW calipers on the R52 while also installing the 316mm front and 280mm rotors?

Some kits like the Brembo and Wilwood BBKs include mounting bracket extensions. I'm curious if these are needed also if installing the R56 JCW stock calipers along with the 316mm rotors.

I have the R56 rear trailing arms, so my concern is more regarding the front rotor size (316mm) fitment on the R52.

Thank you for any two cents.

 

See my topic on the Budweg remanufactured R56 JCW (Brembo) calipers. No bracket is needed if you're using the JCW 4 piston Brembos. Bolt up the caliper, the 316x22 disc, and a set of R56 lines. Wheel choice, however, is another topic. I doubt even that all 17" wheels will even fit with this conversion. 16" wheels are a definite no-go.

 

Planning on running on R136s... currently using R90s. Both seem to be okay with the BBKs.

Thanks for the confirm.
